That is a Roadrunner based on the cowling. The cowlings that Ralph Almirola sold with these boats is made from plastic. Check that and if it is plastic it is probably a Roadrunner. All the shapes look like Roadrunner. Some people have copies them over the years, so it is not certain if it is an original or copy.
With a total refurbish, the boat should be competitive with a good engine and prop. The hardware is good quality stuff.
